2015 Review of the Gas Bulletin Board Zones

Current Status: Closed. The IMO's Final Report was published on 2 November 2015.

Background: The Gas Bulletin Board (GBB) commenced operation in 2013 to improve the transparency of information, security of supply and to facilitate competition in the WA natural gas market. To show where natural gas is being supplied and used across the state, much of the information on the GBB is published by Zones. In accordance with subrule 82(2) of the GSI Rules, the IMO must review the GBB Zones at least once in each five year period or may do so at any point in time. In addition, subrule 82(3) requires that a review of the Zones must be carried out in consultation with Gas Market Participants and gas industry groups.

The IMO engaged Marsden Jacob Associates, an independent consultant, to assist the IMO in undertaking the GBB Zones review.

The IMO invites all sectors of the Western Australian gas industry, including end-users, to make submissions on the draft report. For details on how to provide submissions please see the below invitation.
